    Answer:

    y = 2.76 [m]

    Explanation:

    We can find the distance of the fall of the apple using the following kinematic equation, we have to emphasize that this is a typical problem of free fall, so the initial speed is zero, then we give the initial data.

    t = time = 0,75[s]

    g = gravity = 9.81[m/s^2]

    v0 = 0

    y = v_{0}*t+0.5*g*t^{2}\\ y=0.5*(9.81)*(0.75)^{2}\\y= 2.76[m]
